DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm that the TSSOP-28 package matches your PCB footprint requirements. Ensure the 60 V maximum input rating aligns with your system's peak voltage conditions. Check for RoHS compliance documentation if required by your manufacturing standards.

DC DC Switching Controllers Selection Notes

Select this component when designing dual-output boost converters or interleaved phases for reduced input ripple. The wide frequency range allows optimization for size versus efficiency trade-offs. Consider the 150°C junction temperature capability for harsh environments. Verify that the non-synchronous design meets your cost and complexity constraints compared to synchronous alternatives.

DC DC Switching Controllers Part Context

This part belongs to the LTC7840 family of high voltage DC/DC controllers. It complements other Analog Devices power management solutions like the LTC7811 and LTC7815.
